It was during this period, under a constant barrage of enemy fire, when Wojtek fulfilled his duty as a true soldier. He had observed his comrades who continually loaded and unloaded heavy shells and boxes with ammunition. At one moment the bear walked toward a supply truck on his hind legs, stretched out his paws and waited for the soldiers to give him something to carry. To their amazement, Wojtek effortlessly lifted a heavy box of ammunition and carried it from one truck to another and returned for more. Filled with enthusiasm, the bear marched day after day and carefully carried vital supplies until the Polish soldiers took Monte Cassino. Astonishingly, Wojtek was so careful that he never dropped a single shell, food sack or box with ammunition.
